Cellulose Acetate (CA) Syringe Filters - SF18326

Biotechnology and pharmaceutical laboratories require high-flow prefiltration for large-volume biological samples where coarse particle removal must occur under sterile conditions without compromising processing speed or introducing contamination risks. Advanced 1.2µm cellulose acetate membrane technology with integrated polypropylene prefilter delivers exceptional 180ml flow rates and ready-to-use sterile integrity. Gamma-sterilized 30mm diameter construction with validated 5.8psi bubble point provides the operational capacity your workflows need when processing turbid aqueous samples demanding throughput and microbiological control.

Key Cellulose Acetate Membrane Characteristics

• 1.2µm pore size removes coarse particulates and cellular aggregates from biological samples, providing prefiltration protection for downstream analytical equipment and finer membranes in multi-stage processing
• Hydrophilic surface chemistry processes aqueous solutions immediately upon opening the sterile package, eliminating pre-wetting steps that introduce contamination risks in aseptic laboratory environments
• Low protein binding affinity maintains biomolecule integrity throughout prefiltration, essential when your downstream analyses depend on preserving accurate protein concentrations across sample preparation workflows
• Validated 5.8psi bubble point ensures consistent pore structure and reproducible particle removal, supporting quality control requirements in regulated pharmaceutical and biotechnology applications
• Aqueous buffer compatibility enables processing of biological media and formulation solutions without membrane degradation, though organic solvent applications require alternative membrane materials

Key Construction Characteristics

• 120µL holdup volume optimizes sample recovery in high-volume applications, minimizing material loss while accommodating the integrated polypropylene prefilter that extends operational capacity
• Integrated polypropylene prefilter captures gross debris upstream of the cellulose acetate membrane, preventing premature clogging when your samples carry heavy particulate loads
• Gamma-sterilized polypropylene housing delivers ready-to-use sterile integrity straight from the package, eliminating autoclave delays and supporting time-sensitive aseptic processing schedules
• Luer-Lok and Luer Slip connections provide universal compatibility with sterile syringes and aseptic transfer systems, integrating seamlessly into validated cleanroom workflows

When your laboratory processes large-volume biological samples requiring both high flow rates and sterile handling, standard membranes compromise either throughput or microbiological control. The 30mm gamma-sterilized platform with 4.9cm² cellulose acetate membrane delivers exceptional 180ml flow rates and 110ml throughput per device. Combined with integrated prefilter protection and low protein binding characteristics, this configuration ensures your laboratory achieves the processing efficiency essential for high-volume sterile prefiltration in pharmaceutical, biotechnology, and environmental applications.
